Also duplexes really don't do much harm to the "suburban" feeling of a neighborhood. A nice, big duplex feels as much like a home as any other.

If anything, I feel like it helps make neighborhoods more dynamic by increasing the population density without increasing the physical density of buildings and roads.

That said, parking will be important (need enough room for garages or lots of on-street parking) since I assume these areas won't have great mass transit.

IIRC the latest revisions of sb50 in California would have rezoned the whole state to allow fourplexes (while still upcoming even higher to 5 stories along transit corridors).

But it was blackholed for at least a year by the supreme chancellor of the senate (or whatever her official title is) even though it likely has enough votes to pass if it would have gone to the floor.

That’s democracy I guess?
